PTO stands for what?

• A. Power Take Off
• B. Primary Turbine Outlet
• C. Pressure Take Off
• D. Power Transfer Output

Answer: (A)

PTO stands for Power Take-Off, a drive that taps power from the engine or transmission to run other equipment. In a helicopter like the UH-60S, the PTO is what powers ancillary systems such as hydraulic pumps and electrical generators by taking power off the main drive train rather than using the rotor drive itself. This makes it possible to run essential accessories without needing a separate power source. Other options don’t fit common aviation terminology. Primary Turbine Outlet isn’t a standard term for a power-sourcing mechanism, Pressure Take Off isn’t used to describe auxiliary power drives, and Power Transfer Output isn’t the established acronym for this function.
